android
Build, review, and refactor Android mobile apps (Kotlin) using modern Android patterns. Use for tasks like setting up Gradle modules, Jetpack Compose UI, navigation, ViewModel/state management, networking (Retrofit/OkHttp), persistence (Room/DataStore), DI (Hilt/Koin), testing, performance, release builds, and Play Store readiness.
Best use case
android is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using android should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# android Use this skill when working on Android client (大前端 / 移动端) codebases. ## Defaults (unless repo dictates otherwise) - Language: Kotlin - UI: Jetpack Compose (if legacy XML exists, follow existing structure) - Architecture: MVVM + unidirectional data flow (UDF) - Async: Kotlin Coroutines + Flow - DI: Hilt if present; otherwise keep consistent with current ## Project structure (recommended) - `app/`: application module (entry, navigation, composition root) - `core/`: shared utilities and platform abstractions (optional) - `data/`: API + persistence implementations - `domain/`: use-cases, business models (pure Kotlin) - `feature/<name>/`: feature modules or packages (UI + presentation) ## Workflow 1) Establish constraints - Min/target SDK, build system, existing modules. - Compose vs XML, single-module vs multi-module. 2) Define app flows - Identify screens and navigation graph. - Define state models per screen and their events/actions. 3) Data layer design - API models vs domain models (mapping boundaries). - Retrofit service interfaces + OkHttp interceptors (auth, logging). - Caching strategy: memory vs disk (Room/DataStore). 4) UI & state - Compose: keep Composables stateless where possible; state hoisted to ViewModel. - ViewModel exposes `StateFlow<UiState>` and accepts events/intents. - Handle loading/error/empty states explicitly. 5) Error handling - Normalize errors (network, auth, validation) to domain-friendly types. - Avoid leaking Retrofit/Room types into UI. 6) Performance & UX - Avoid recomposition traps; use stable models and `remember`. - Images: Coil; pagination for long lists; debounce inputs. - Accessibility basics: content descriptions, large text support. 7) Quality gates - Unit tests for domain and ViewModels. - UI tests where meaningful (Compose testing). - Lint/detekt/ktfmt if configured; keep build green. ## Output expectations when making changes - Keep diffs localized; avoid broad refactors unless requested. - Add/adjust tests when changing behavior. - For new features: include navigation entry, UI state contract, and data wiring.
